RAILWAY SWITCH.

Application filed May 8,

of Montana, have invented certain new andv useful Improvements in Railway Switches, of which the following is a specification.

My invention relates to railway switches and operating mechanisms therefor, and its principal object is to provide a railway switch and operating mechanism wherein the points of the switch may be operated from the train passing the switch from either direction.

A further object of the invention is to provide a railway switch'operating mechanism embodying elements arranged forwardly and rearwardly of the switch points and connected with the latter and trips carried by the train for engagement with either one of the elements for first setting the switch points and after the train passes the switch engages the other element to return the switch points to inoperative position.

Still another object of the invention is to provide a railway switch and operating mechanism therefor which may be installed in any railway and will not necessitate the altering of the switch points and may be installed at a comparatively small cost.

With the preceding and other objects and advantages in mind, the invention consists in the novel combination of elements, yconstruction and arrangement of parts and operations to be khereinafter specific-ally referred to. claimed and illustrated in the accompanying drawing, wherein- Figure 1 is a top plan view of a railway switch embodyingrmy invention.

Figure 2 is a transverse sectional view showing a portion of a car.

Figure 3 is a detail view of the pulley.

Figure 4 is a detail view of the drum and gear.

Referring in detail to the drawing wherein corresponding characters of reference denote corresponding parts throughout the several views, the numeral 5 denotes a railway track having a siding y6 and a pair of guide 1923. Serial No. 637,535.

pivoted switch points 7 the free ends of which being connected with a transversely shiftable bar 8.

Arranged in advance and rearwardly of the switch points 7 are horizontally arranged gear wheels 9 arranged for longitudinal and rotary movement between oppositely disposed rack bars 10 which are slidable in guides 11 and serve to hold and guide the gears 9 when operated. Drums 10 are fixed to the underface of the gears 9 and engaged about the drums and extended around the same in reverse directions are cables 11 each of which is extended towards the switch points and engaged with pulleys 12 and then extended in divergent relation and attached to the transversely shiftable bar 8 adjacent the ends thereof.

Each of the gears 9V is provided upon its upper face with a pair of right angularlv disposed beveled trip engaging members 13, one of each pair of which being normally disposed in the path of a strip 14 depending from a railway car 15. In the operation of the mechanism the parts being in the relative position shown in Fig. 1 the strip 15 engages the switch engaging element--t-o rotate its gear whereby to wind the cable therevaround and shift the bar 8 toY move the switch points into operative position. After the train passes the switch points the trip engages the switch engaging member of the v other gear to rotate the same and wind its cable-about the drum and operate the bar 8 into the `reverse direction to move the switch points to normal position.

V`From the foregoing it will be seen that I have provided a simple, inexpensive and eflicient means for carrying out the objects of the invention, and while I havepar ticularly described the means best adapted to perform the functions set forth,- various changes in form,'proportion andv in the minor details of construction may be rev sorted to without departing from the spirit or sacrificing any of the principles ofthe invention.

What claim as new and l desire to secure by Letters Patent is:-

The combination with a milway track? a l00 pair of pvoteol switch points', of a pair of rotatable elements one ofv which being arranged n advance of the switch points and the other rearwardly thereof, cables connected with each of the rotatable elements and the switch points and elements carried by the rotatable elements adapted to be en gaged by a strip carried by the train to rotate one rotatable element to Set the switch points and subsequently rotate the other rotatable element to open the swtchpontsv In testimony whereof I aX my signature.
